Many companies rely on SQL-compatible databases for their reliability, yet non-technical users often struggle with complex SQL operations. To address this, organizations develop internal tools to facilitate basic CRUD (Create, Retrieve, Update, Delete) operations on databases. This tutorial demonstrates how to use SQL statements for these operations, with the example of creating a CUSTOMER table in a SQL database. It covers inserting records, retrieving data using SELECT statements, updating records with the UPDATE command, and deleting entries with the DELETE command. The tutorial also highlights the importance of SQL syntax consistency across different database dialects, such as MySQL, PostgreSQL, and Oracle. It concludes with a nod to Retool, a platform that simplifies building internal applications by providing a UI toolkit for displaying and visualizing data, and announces new usage analytics features for better team and app management.
